Abstract

The invention provides a wind power paddle changing control system, comprising: a paddle changing motor for adjusting angle of paddles of a wind power station; a paddle driver connected with the paddle changing motor and used for controlling operation of the same, wherein the driver is electrically connected with an external power supply; and a standby power supply for supplying emergency power for the paddle changing motor, wherein the standby power supply is connected with the paddle changing motor; the driver is electrically connected with the standby power supply to charge the standby power supply with the external power supply. The wind power paddle changing control system has the following benefits: a charger is integrated in the driver, so that components and parts are saved, and installation and distribution of wires and devices are simplified; and charging of the driver is not limited by a transformer, so that charging is efficient and reliable.

Description

technical field [0001] The invention relates to a wind power pitch control system, in particular to an I / O port and an A / D port of the wind power pitch control system. Background technique [0002] The development prospects of the new energy power generation industry are very broad, and vigorously developing wind power is the focus of my country's new energy strategy. At the current stage of wind power development, how to make it cost-effective to form a competitive advantage with coal power and hydropower is the goal pursued by the wind power industry. While continuously improving reliability, reducing cost is the development direction of all wind power generation equipment. [0003] The pitch control system is an important component in the wind power generation system, and the motor driver 1 is one of the key components of the pitch control system. In order to make the pitch control system work reliably and stably in the event of a momentary power failure, and to be able...
